parisneo/lollms-webui: External Control of System or Configuration Setting
CVE-2024-4326 is a critical-severity external control of system or configuration setting vulnerability in parisneo/lollms-webui from ParisNeo, with a CVSS 3.0 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 9.5 as the first without the flaw, so updating parisneo/lollms-webui to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.97% chance of exploitation within 30 days, higher than 62% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update parisneo/lollms-webui to 9.5 or a later version.
- Update lollms-webui to 9.5 or a later version.
- Update Lollms Web UI to 9.5 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability in parisneo/lollms-webui versions up to 9.3 allows remote attackers to execute arbitrary code. The vulnerability stems from insufficient protection of the `/apply_settings` and `/execute_code` endpoints. Attackers can bypass protections by setting the host to localhost, enabling code execution, and disabling code validation through the `/apply_settings` endpoint. Subsequently, arbitrary commands can be executed remotely via the `/execute_code` endpoint, exploiting the delay in settings enforcement. This issue was addressed in version 9.5.

The underlying weakness: External Control of System or Configuration Setting
One or more system settings or configuration elements can be externally controlled by a user.
How developers prevent this class of flaw
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
- Because setting manipulation covers a diverse set of functions, any attempt at illustrating it will inevitably be incomplete. Rather than searching for a tight-knit relationship between the functions addressed in the setting manipulation category, take a step back and consider the sorts of system values that an attacker should not be allowed to control.
- In general, do not allow user-provided or otherwise untrusted data to control sensitive values. The leverage that an attacker gains by controlling these values is not always immediately obvious, but do not underestimate the creativity of the attacker.
